EXPANDING STOPPEJR.

(No model.) Patented in England March 4, 1889, No. 3,752; in France De- 1889, and in Belgium December 16, 1889. 7

To all whom it may concern; Be'it known that I, BENJAMIN HAIGH, a subect of the Queen of Great Britain, residing at Isle of Dogs, London, England, have invented certain new and useful Improvements in Stoppers for Bottles, Jars, and the Like, (for which I have obtained patcuts in the following countries: Great Britain, plied for December 12, 1889; Belgium applied tor Dece'mber l 6,.l889,) of which the followmg is a specification.

Myinvention relates to an improved selfcontamed stoppering device for closing the mouths or openings of bottles and jars, appliother containing vessels or receptacles and for other similar purposes.

In the accompanying drawings, illustrative of my said invention, Figures 1 and 2 are vertlcal sectional elevations; Fig. 3, a horizontal section on line A B, Fig. 1; and'Fig. at, elevatlonal views of the various parts shown detached of my improved stoppering device, adapted for closing the mouths of bottles and like vessels. Fig. 5 represents a sectional elevation of a jar having my improvements adapted thereto.

In Fig. 2 the stoppering device is shown in Figs. 1 and 5 show the stopper inserted in the mouth of the bottleor recess is formed opening of the vessel but not screwed home.

The stoppering device (shown in Figs. 1 to 4, inclusive,) comprises a preferably wooden plug A, bored centrally with a recess throughout its longitudinal axis and provided with a flange rim or capsule a, resting on the mouth of the bottle, being formed either in combination with A or separately, and by means of which the plug A is suspended in the mouth of the bottle. A circumferential groove or on the lower convex surface of said plug, which is fitted or surrounded with a flexible ring, gasket, or annulus B, of any suitable material, such as india-rubber or the like, projecting sufficiently past the end and of a diameter, when in position, corresponding to that of the plug A, so as to permit of the ready insertion of the stoppering device in the bottle-mouth. A sleeve-picce 0, formed with an internal screw-thread, slides dated March 4, 1889; in France ap plug, its rotation being prevented by a pro- I jection or web 6, working in a groove formed 1 in the interior of the Fig. 2, which is passed transversely through the plugA and the longitudinal slots or guides formed in the sleeve-piece C. Thi sjatter, which is providedwith a conical termination c, is raised orlowered on rotating the screwed .plug D by its milled head (1, Figs. 1 and fl, or

by its winged termination d, Fig. 2.

plug A, or by a pin 1), ts

When the stoppering device is inserted in i the mouth of the bottle and the sleeve 0 raised on rotating the screwed plug or bolt D, the conical termination c of the sleeve 0 is raised or drawn up also, and so expands the flexible ring or annulus B, which expansion serves effectually to close the mouth of the bottle. The screwed stem or plug D, which is formed with flanges e 6', working oneyon each side of the capsule or flange a of the plug A, is cut with a quick screw-thread corresponding to that of the sleeve 0, so that a half-turn will be sufficient to lock the stopper in the mouth of the bottle, or vice versa. To limit the rotation of the screwed plug or stem D and so prevent the accidentalseparation of the parts, the flange e, which partially rotates in the recess formed below the capsule a in the plug A, is formed with a projection e, engaging with the stop-pin 6'.

Fig. 5 is a sectional elevation of my stoppering device adapted for closing the mouth of a jar or wide-mouthed bottle or the like. The construction and working of the device here shown is exactly the same as that previously described with reference to Figs. 1 to 4, save only that the several. parts are necessarily enlarged to coincide with theincreased size of the opening of vessel to be closed.

I am aware that prior to the date of invention it has been proposed to employ bottle and like stoppers fitted with a ring or gasket of flexible material expanded or compressed by means of a conically-headed plug or bolt raised by a-screw-threaded sleeve or nut. I therefore make no claim, broadly, for such a combination; but

What I claim is v A stopper for bottles, jars, and the like, comprising a downwardly-projecting hollow plug A, suspended by a flange or capsule a, combined with a bolt or stem D, formed with a In testimony that I claim the foregoing as screw-thread at its lower end and provided my invention I affixmy signature in presence I0 with flanges e e, stop-piece a, and pin of two Witnesses. an internally-soreW-threaded sleeve-piece C,
